Incoming Gateways

The purpose of an incoming gateway is to reduce server load. Generally, spam checks and antivirus scans should be performed on the incoming gateway, freeing up the primary server processing for the delivery of messages.

To access the incoming gateway settings, click the settings icon. Then expand the Routing folder and click Incoming Gateways in the navigation pane. A list of incoming gateways will load in the content pane.

To add a new incoming gateway, click New in the content pane toolbar. To edit an existing gateway, select the desired gateway and click Edit. The incoming gateway settings will load in the content pane and the following tabs will be available:

Options

Use this tab to specify the following settings:

  • Gateway Mode - The function that the incoming gateway will perform. If the incoming gateway is set to backup MX, it will only receive messages when your primary server is down. If the incoming gateway server is set to domain forwarding, it will received all message and forward them to your primary server.
  • IP Address / IP Range - The IP address, or range of IP addresses, of the primary mail server.
  • User Verification - The method used by the incoming gateway to determine if a user is valid or not. Note: If none is selected, the incoming gateway server will accept all email addresses for the domain. If Web service is selected, the incoming gateway will check with the primary mail server for a list of valid email addresses.
  • Enable SmarterMail Gateway Mode - Select this option to indicate that the incoming gateway server is another SmarterMail server.
  • Disable Greylisting - Select this option to disable greylisting for the domain.

Domains

This tab is only available if the gateway mode is set to domain forwarding. Domain forwarding allows you to easily send mail through one server to another. This will allow your server to act as an incoming gateway to your network, and permit you to have a single point of entry for incoming SMTP traffic.

When messages come in to a forwarded domain, they are run through the command-line exe referenced in Protocol Settings. If a delivery delay has been established for the server, messages are also delayed accordingly. This allows you to establish an incoming server that can run external virus or spam scanners, which can reduce the load on your existing network servers.

Use this tab to specify for which domains the incoming gateway will accept mail:

  • Domain Verification - The method used by the incoming gateway to determine if a domain is valid or not.
  • Specified Domains - The specific domains for which the gateway will accept mail.

Spam

Use this tab to specify the following spam checks:

  • Not Spam Action - The action the incoming gateway will perform on messages NOT marked as spam.
  • Spam Low Action - The action the incoming gateway will perform on messages with a low probability of being spam.
  • Spam Medium Action - The action the incoming gateway will perform on messages with a medium probability of being spam.
  • Spam High Action - The action the incoming gateway will perform on messages with a high probability of being spam.

SmarterMail Gateway

This tab is only available if the SmarterMail gateway mode is enabled in the Options tab. Use this tab to specify the following settings:

  • SmarterMail URL - The Webmail URL for the SmarterMail server being used an an incoming gateway. This will allow the use of Web services to verify the users and domains.
  • SmarterMail Username - The identifier used to login to the primary mail server.
  • SmarterMail Password - The corresponding password used to login to the primary mail server.
